Calculate the speed that a gas-phase fluorine molecule would have if it had the same energy as an infrared photon (λ = 1.00 × 10⁴ nm), a visible photon (λ = 500. nm), an ultraviolet photon (λ = 100. nm), and an X-ray photon (λ = 0.100. nm). What temperature would the gas have if it had the same energy as each of these photons? Use the root mean square speed, v _rms = (v²)^1/2 = √3k_BT/m for this calculation.
